The Global Water Crisis Is Real and Urgent.

January 2026. The United Nations officially declared the beginning of an era of "global water bankruptcy." This is not a temporary crisis, but a structural transformation of the world's water reality. According to the UNU-INWEH report, many regions are already living beyond their hydrological capacity, and numerous critical water systems are effectively "bankrupt."





Figures That Demonstrate the Urgency

More than 2 billion people lack access to safe drinking water
In the European Union, only 2.4% of the 40 billion m³ of wastewater is reused
By 2030 (in four years), water stress will affect 50% of European river basins
The potential cost of a production stoppage due to water issues in critical industries (pharmaceutical, semiconductors) is more than €1 million per hour
In Jordan, only 61 m³ of fresh water are available per capita per year (the absolute scarcity threshold is 500 m³)
In Latin America, the situation is equally critical. Although the region concentrates nearly 34% of the planet's renewable fresh water, water scarcity stemming from droughts and basin degradation today affects more than 100 million people, and less than 50% of wastewater is properly treated (Source: ECLAC)
These reports leave no room for doubt: water stress has become the new normal, threatening access to this vital resource and igniting conflicts among users. The time to invest in water security is now.

The Invisible Cost of Inaction

In times of geopolitical turbulence, ensuring environmental security becomes a matter of survival and independence. As global populations grow, resource demands increase, and environmental challenges accelerate and converge toward possible security crises. Veolia positions itself in favor of global environmental security.

The company worked with researchers from Columbia University and HEC to define environmental security as "the stable condition in which people and communities possess the essential resources and capacities to manage, plan, and effectively adapt to the future amid interconnected challenges linked to the accelerated changes in our human ecology and the environment."

Far from being a theoretical problem, global environmental security is based on local realities and human impact, to ensure the health and quality of life of local communities. It also ensures access to vital resources for industry and agriculture, long-term predictability for investors, and resource sovereignty for governments. And it reaffirms the principle that these benefits are closely intertwined.

Veolia's commitment to environmental security goes beyond emergency solutions and risk mitigation: it aims for system resilience. It contributes to a world that anticipates and plans ahead.

Far from being just another constraint, environmental security is an investment in the capacity to absorb impacts, adapt to change, and foster well-being.

Existing Solutions: Water Reuse

Advanced Treatment Technology Is Within Reach

Advanced treatment solutions exist that are capable of producing water meeting the standards required for municipal, agricultural, and industrial uses. The real problem is not knowledge, but the scale of implementation.

Proven Benefits of Reuse

Return on Investment: According to the OECD, every dollar invested in adapting and increasing infrastructure resilience can generate $4 in benefits over the asset's useful life and reduce future losses.

Guaranteed Access: Water reuse facilities represent a significant investment to meet critical needs. They are part of the solutions that help communities and businesses to:

Reduce exposure to water shocks
Stabilize operational costs
Improve long-term performance
Guarantee regular access to drinking water
Transforming Constraints into Opportunities: Water reuse is a way to turn ecological constraints into levers for strengthening resilience and competitiveness.

Four Strategic Pillars to Unlock Water Reuse

Veolia identified four strategic pillars that function as keys to unlocking water reuse at a global scale. These pillars are not independent; they work in an integrated and systemic manner.

PILLAR 1: REGULATION

Water reuse is often approached as a short-term response to water stress, rather than as a long-term water security strategy. In many contexts, it is also not considered at the right scale, where upstream-downstream dynamics, environmental flows, and competing uses can be properly evaluated.

While health and environmental safeguards are essential, overly strict or over-harmonized standards can slow innovation and deployment.

Elsy Milan, Postgraduate Researcher at Imperial College London and Political Negotiator at UNFCCC, comments on this: "Unlocking regulations means bringing everyone to the table: regulators, scientists, shaping a future that begins with awareness up to financial incentives."

Solutions such as long-term planning at the right scale and context-adapted regulation (intended use, hydrology, institutional capacity and country maturity, among others) are key to strengthening this pillar.

PILLAR 2: SOCIAL ACCEPTABILITY

While the acceptability of reuse varies by use and local context, direct potable reuse remains the most socially sensitive application.

Psychological barriers are real. People may feel uncomfortable drinking recycled water, as they "instinctively think of it as toilet water," an image difficult to shake even knowing it has been purified. In addition, concerns about medication residues, bacteria, and microcontaminants arise.

However, there is positive news: results from the Ecological Transformation Barometer, a survey conducted by Veolia and Elabe in 2025, show that 66% of respondents would accept drinking tap water partially derived from recycled or reused wastewater to reduce the risks of water scarcity for consumption, agriculture, and the country's economy.

Key Data Point: Direct Potable Reuse

Direct potable reuse involves redistributing water as tap drinking water after exhaustive treatments and testing. Although the end result is the same, it is more socially sensitive than "indirect potable reuse," where water is stored and mixed with other "natural" water resources in a lake, river, or groundwater aquifer before returning to the pipes.

PILLAR 3: ECONOMIC MODELS AND FINANCING

Actors face a central paradox: water is undervalued, but there is an excessive price to pay when it is absent. Reused water has a cost, frequently higher than conventionally obtained water. Pipes and other transport infrastructure are generally the most expensive part of the system, particularly in agriculture (where it can be 20 times more expensive than treatment cost alone).

On the other hand, the absence of water is neither measured nor considered, both at the individual and territorial levels. What is the price of water scarcity? How much does a failed harvest cost, stopping industrial production for one hour, or leaving citizens without tap water for several hours or days?

Esther Crauser-Delbourg, Water Economist, makes it very clear: "Without water, there is no life, no economy, no international commerce. So water needs to be shared. All local users need to sit around the table and talk about water: how much they need, how they can adapt to scarcity, about tariffs and prices that reflect the value of water."
